I came across something that could be usefull, adding a "If Contain" Operator in condition set (For Multipick list only)
Instead of only having the choice for Equals and Not Equal. If the person select "If Contain" or "Contain" well we would be able to do more precise conditions.
Example: The end user fill the Service Catalog they have a field where they can select what type of access they need (Dynamics 365).
Because the field "Dynamics 365" is selected well it send an email to somebody in the company if not selected, it doesn't send the email.
